Holey Grail Donuts started selling its hand-fried, made-to-order taro donuts on Sunday mornings out of a little red burger trailer in Kauai in 2018.

Four years and hundreds of long lines later, the truck is still there, but the company is taking on what co-founder Nile Dreiling calls “a stale $40 billion donut industry” by expanding its presence into brick-and-mortar locations in Los Angeles after raising $9 million in financing.
